About the CS 40
Std. keel: 6.58'/2.01m Tot. SA: 800.15 ft2 /74.33 m2
The CS 40 is a classic Canadian Sailcraft design by Tony Castro, with production records indicating a build year of 1987. As a 39.25 ft LOA masthead sloop with a displacement of 17000.0 lb, it represents a substantial, heavy-displacement cruising platform from the late 1980s.
- Best for:
- This boat is best suited for experienced coastal cruisers and those seeking a comfortable, stable passage-making vessel, given its high comfort ratio of 25.78 and substantial ballast of 7500.4 lb.
- Bluewater capability:
- With a low capsize ratio of 1.97 and a displacement-to-length ratio of 217.65, the CS 40 exhibits strong inherent stability and seakeeping characteristics suitable for offshore passages.
- Comparables:
- Comparable vessels include the Cal 40 and O'Day 38, which share similar displacement ranges and beam dimensions (12.67 ft), offering a balance of interior volume and offshore capability.
